What else can I help you with?
If you know a woman has hemophilia what can you infer about her parents genetype?
Her father has to have hemophilia as well, and the mother is a carrier or also has hemophilia. So if we pretend that the hemophilia gene is "x", you need to have "xx" to have hemophilia. The father must have the genotype "Yx" and the mother has the have "Xx" or "xx".
What is the probability that their son has hemophilia?
Hemophilia is passed down from mother to son. It is extremely rare for a woman to have hemophilia. It is necessary, though, for a woman to be a carrier of the disorder for her son to acquire this disorder. Females have two X chromosomes whereas males only have one. When a boy is born, he takes one X chromosome from his mother and one Y chromosome from his father. Therefore, he can only get hemophilia through his mother. Example One: Mother(Carrier)+Father(Non-Affected)=50% chance of their son acquiring the disorder and 50% chance of their daughter being a carrier. Example Two: Mother(Non-Affected)+Father(Hemophiliac)=All sons will be non-affected and all daughters will be carriers.
When the dna results come in will there be something on the dna test about the y chromsome This is a paternity test of a child.?
The Y chromosome will be included in the DNA test that determines paternity, because as we all know, half of our DNA comes from the mother and the other half from the father, which makes up the full genetic profile of the child with both x and y chromosome pairings.
Is know as the father of gentetics?
Gregor Mendel is known as the father of genetics. He conducted experiments with pea plants in the 19th century and discovered the basic principles of heredity and how traits are passed from one generation to the next. Mendel's work laid the foundation for modern genetics.
What information on a pedigree can tell yo whether a gene is on autosome or on a sex chromosomes?
You can tell by the patterns and, to a lesser extent, ratios of trait inheritance. Both sex-linked and autosomal traits can be dominant or recessive and the patterns for each type are different. Usually for autosomal inheritance there isn't a difference in the ratios between males and females affected with the trait while in sex-link inheritance there is. If there are traits that seem to skip a generation then they usually are recessive. Genes that are located on the Y chromosome are passed from father to son, never to daughter whereas genes on the X chromosome can go to both. It's important to know that since normal human males only have one X, X-linked traits will be dominant for them whereas for females the trait can manifest in one dose (haplosufficiency) or would have to be in two doses (both X's would have to have the gene).
1 Why is the Y chromosome particularly useful for tracing human genetic history?
It is only passed from father to son, so it provides a direct lineage. If a person is discovered to have a unique marker, you know that everyone else in the world that has that marker is descended from that one person.

You have had a rented property passed down from your father is it possible to pass it down to your son?
My father had a farm passed down to him from his father it was rented and now i would like to know if I could have the farm passed down to me I'm the 3rd generation is it possible
If a baby is formed by an X chromosome from mother and Y from father would Jesus have only one X from Mary even though you know it is God's work?
Whether or not a particular religion sees Jesus as divine or not, if he was human at all he had to have the XY chromosomes. One can assume that, if actually conceived by the Holy Ghost, the Holy Ghost has the ability to provide a Y chromosome...
Then does that mean that my father isn't my real father?
Sorry i don't know for sure but, i think it means that your father now is your step dad. You real father has passed away or has ran away.

A trait controlled by a gene on the sex chromosome is know as a?
A trait controlled by a gene on the sex chromosome is known as a sex-linked trait. These traits are often inherited in a sex-specific manner, with different patterns of inheritance depending on whether the gene is located on the X or Y chromosome.
Fern A has a chromosome that makes its leave rough fern B has a chromosome that makes its leave of the new plant be smooth or rough how do you know?

How do you know the set of chromosomes is from a male?
If it has a x and y chromosome it is from a male if it has two x chromosome or is from a female
How do you know if you pass a drug test from driver check?
Well, you should know whether you passed it or not before you take it? So, "You know you've passed beforehand if you haven't taken any illicit drugs beforehand." But places were obliged to tell you if you had failed, although the veracity of this info is now out-of-date.
Can they make you take a DNA test if you know your the father?
Whether you "know" it or not, is not the question - if you are refusing to acknowledge that fact and are disputing it, yes, the court (or whatever government agency) CAN require it.
